Before 1826 the peso was a name often used for the silver Spanish eight-real coin. Following independence, Argentina began issuing its own coins, denominated in reales, soles and escudos, including silver eight-real (or sol) coins still known as pesos.
These coins, together with those from neighbouring countries, circulated until 1881.Between 1881-1970, gold coins of 5 and 2.5 pesos were to be used, silver coins of one peso and 50, 20, 10 and 5 centavos, and copper coins of 2 and 1 centavos.
